Does Your System Sound Like the Real Thing?

Some live performances sound pretty bad... some recordings have excellent sound. In a very good large hall if you're 100' away from the musicians you'll miss alot of nuances that are easily picked up in a good nearfield playback environment. I probably haven't heard anything near the best possible playback system, (there may not be one that does everything the best), but so far the best live stuff knocks the stuffin's outta the best recorded stuff w/ out breaking a sweat. The two things are just physically (and psychologically) very different from each other. Then there's the can of worms regarding the perception of musical or artistic merit vs. recording quality (who wants an exquisitely detailed rendering of something that hits the gag reflex?). There are lots of acts that might make you head for the door on their most sonically perfect night. Then sometimes when you least expect it you could end up really liking some stuff that you used to hate.

No and No.

your system is indistinguishable from live performances

No way.
One system might fool you -- but that's a musicality issue. The other is higher rez -- but that's "true to SOURCE" i.e. the recording, NOT the musical event.

IMO that's all we can achieve -- and it's not bad after all: either a "musical" sound reproduction OR a "true to source" reproduction. Whatever tickles our collective fancy.

So,

If the answer is no, do you even think it's possible

Of course not.
Not only are recording techniques & storage media a limitation; the speakers & spkrs-room interaction are even more so, as Ohlala notes above.

BTW, and similarly, a portrait is NOT the actual person, is it? It's an artist's interpretation and rendition of that person. (I'm putting sound reproduction on a high pedestal here:))

If you are taliking "hypothetical" live performance where everything is perfect (seating position, no crowd noise, acoustically perfect venue etc) then no stereo not as good as live.

But if you are talking about "real world" live performces with all the imperfections then I usually prefer my stereo to almost any live performance soundwise. Of course part of the attraction is the visuals which is lacking with stereo.

I always wonder where people hear these mythical perfect live performances that they hold up as gold standard that no stereo can match?

No.

Live music,as a time art,includes the thought processess of the performers, the listeners, and the venue. A piece of music is never performed the same way twice.
